Disc Brakes

More and more people are switching their trailers over to disc brakes, and with good reason. Disc brakes deliver consistent braking - even at highway speeds - unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a substantially shorter stopping distance than drum brakes.


Disc brake calipers have only one moving part, rather than the many found in drum brakes. This means that there are fewer parts to maintain, fewer parts to get damaged and fewer parts to have to repair or replace, thus reducing maintenance costs.


Over-the-Hub Rotor

Kodiak's slip-on, cast iron rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.


Calipers

Kodiak calipers are constructed of cast iron to prevent flexing. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant stainless steel piston is 30 percent larger than standard pistons, ensuring shorter stopping distance and increased torque. In addition, the unique low-drag design of Kodiak's calipers allows the piston to retract farther than in most standard models, giving you a cooler-running brake.

You folks are awesome on both sides of the house. I got my order and the packaging is the only drawback. Something of this weight really should be shipped in something stronger than a cardboard box.i was missing some pieces of the kits that was handled really nicely by your people on the returns side but boxes are demolished.They sending me a new kit so I can return the kit missing pieces. But I am not disappointed in the product.Keep up the wonderful people you have there.

Installed the K2HR12A11-120DW Kodiak Disc Brake kit 11.35" Rotor-#120 Spindle -12k-ALKO. The kit seems to be really good quality and easy to install, it was installed on a 2011 model PJ trailer and everything fit as it should and the brakes bleed easily also we uploaded pictures of the install. Thanks also to customer service they were really nice and easy to talk with to resolve the shipping issue that we had.

  • Replacement Rotor For Kodiak Disc Brake Kit # K2HR12A11-120DW and Compatibility
    The Kodiak Disc Brake Kit # K2HR12A11-120DW will use the Kodiak 11" Rotor # KR1110Q which is 11.35" in diameter. Your current rotor only being 10-3/4" will not fit with this kit. The disc brake kit is designed to fit on ALKO 12,000lb axles that use a # 120 spindle. You can verify the fit by checking your current bearings or the dimensions of your spindle. Inner Bearing # TRJM511946(2.559" inner diameter) Outer Bearing # JM205149(1.969" inner diameter) Oil Seal # 10-56(3.125" inner diameter)

  • How To Convert Trailer with 12K Axles from Drum to Electric Over Hydraulic Disc Brakes
    Yes, we do offer disc brakes for trailers with 12,000 lbs axles. I recommend the Kodiak Disc Brake Kit, part # K2HR12A11-120DW for AL-KO or part # K2R1258L12 for Dexter/Lippert (Most Common) axles. If you don't know what axles you have you'll need to crawl under the trailer and find the tag on the beam which will list the axle manufacturer. In order to complete your setup you'll just need the Hydrastar Marine Electric Over Hydraulic Actuator Kit part # CAR-HBA16-2. This works for single...

  • Replacement Hub And Drums For Dexter 12K Axle
    We have the perfect idler hub set up for you! The Dexter Trailer Idler Hub Assembly for 12,000-lb Axles # 8-214-8UC1 has an inner bearing # 3984 and an outer bearing # 28682. The idler hub has a bolt pattern of 8 on 6-1/2 inches. The hub has an oil bath system that allows for easy maintenance. The Drum and Mounting Bolts # 7-103 are sold separately. The Kodiak Disc Brake Kit # K2HR12A11-120DW will not work with your 12K Dexter axle because this kit is only for a 12,000 ALKO axle. The...

  • Is a New Electric Over Hydraulic Actuator Required When Converting from Drum to Disc Brakes
    Yes you will need a new electric over hydraulic actuator to go from drum to disc as the disc brake setups require a higher psi rating. The best option is the HydraStar part # HBA16 as it has the best reputation for reliability and is the fastest reacting as well so it's what we recommend the highest. Since you are going to disc brakes you'll need a flexible line to go from the caliper to the axle since the caliper moves. For that you'd want the part # # T0776500 .

  • Availability Of Replacement For AL-KO 5/8 Hub Assembly 568215
    I am sorry Beth, but we do not offer an equivalent to the AL-KO 5/8 hub assembly # 568215. We do carry replacement bearings for this hub with the # TRJM511946 inner bearing and the # JM205149 outer bearing, but we do not offer any hubs that use this bearing combination or will fit the AL-KO #120 spindle. These sizes have become pretty uncommon these days. The only kit we have for the AL-KO #120 spindle is a disc brake kit # K2HR12A11-120DW, so while this hub would technically fit the...

  • Disc Brake Kit That Fits Hayes/AL-KO 12,000 lb Axle With #120 Spindle
    Yes, your Hayes/AL-KO 12,000 lb axle with a #120 spindle is absolutely compatible with the brake kit you mentioned, the Kodiak Disc Brake Kit # K2HR12A11-120DW. This kit does require you get the bearings and seal separately, but comes with the races so you don't have to purchase those as well. What you will need are two each of the following: - Replacement Trailer Hub Bearing # TRJM511946 - Replacement Trailer Hub Bearing # JM205149 - Seal # 10-56

  • Axle Hub That Uses Bearings JM511946 and JM205149, Race JM511910 and JM205110
    The Kodiak Disc Brake Kit # K2HR12A11-120DW is the only hub we have that uses the Inner Bearing # TRJM511946, Outer Bearing # JM205149, Inner Race # TRJM511910, and Outer Race # JM205110. Those bearings are what fits with an ALKO axles using #120 spindles. If that hub is what you are looking for you will need to purchase the Bearings # TRJM511946 and # JM205149 separately along with a Oil Seal # 10-56 for each hub.

  • Will The Kodiak Disc Brake Kit K2HR12A11-120DW Fit With 16" Wheels?
    The Kodiak Disc Brake Kit - 11.35" Rotor - #120 Spindle - 12K - ALKO # K2HR12A11-120DW can indeed be used with 16" wheels. Due to the diameter of the rotor and size of the calipers, this is the smallest wheel they will be able to be used with. Something commonly missed with this set up is that, though the oil cap is included, the bearings and seals are not. If you are going to be replacing these as well, you will need the following parts to complete each kit: Qty.2 - Replacement Trailer...

  • Which Disc Brake Conversion Kit For 10000lb Dexter Axle Made In 2020
    For your 10000lb Dexter oil bath axle made in 2020 you will need to go with the Kodiak Disc Brake Kit # K2R1058D11E since your axle uses leaf springs, and is not a torsion axle. This will work with dual 16" wheels so you will need to make sure that is what your trailer currently uses. You will need to use Dexter Axle Oil Hub # 008-430-03 for each spindle to allow you to install the above kit unless you already have idler hubs.
